Description

TECHNICAL FIELD

[0001] The utility model relates to connector technical field more specifically relates to a high frequency high current oil -resistant connector. BACKGROUND

[0002] The early development of connectors can be traced back to 1939, when they were mainly used in fighter planes during World War II. With the rise of consumer electronics such as televisions and telephones, connectors expanded from military use to large-scale applications in electronics, automobiles, and computers.

[0003] The high-current connectors currently on the market are mainly used in conventional environments. The conventional ones use circular pinholes. Due to the skin effect of current in a high-frequency environment, the current distribution inside the conductor is uneven, with the current concentrated in the "skin" part of the conductor, i.e., the thin layer on the surface of the conductor. The closer to the surface of the conductor, the greater the current density, and the actual current inside the conductor is smaller. If a conventional high-current connector is used in a high-frequency environment, the outer shape will be very large, wasting materials and occupying a lot of space.

[0004] The oil-resistant connectors currently on the market are all used in conventional environments and cannot meet the requirements of use in high-frequency environments. SUMMARY

[0010] A jack is installed in the front hole insulator, and the jack is sealed with the end face of the front hole insulator.

[0011] A rear insulator is installed on the socket shell to fix the jack.

[0012] In some embodiments, the jack is flat in shape.

[0013] In some embodiments, the end face of the front hole insulator and the mounting cavity is sealed by a first O-ring.

[0014] In some embodiments, the jack and the end face of the front insulator are sealed by a second O-ring.

[0015] In some embodiments, the rear insulator is fixed on the socket housing by a cover plate.

[0032] The following will be combined Figures 1-2 A high-frequency large-current oil-resistant connector related to the embodiments of the present application will be described in detail. It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0033] Embodiment 1:

[0034] As Figure 1As shown, a high-frequency, high-current, oil-resistant connector includes: a socket housing, a front-hole insulator, a jack, and a rear insulator. The socket housing is provided with a mounting cavity; the front-hole insulator is inserted into the mounting cavity, and the front-hole insulator is sealed with the end face of the mounting cavity; the jack is installed in the front-hole insulator, and the jack is sealed with the end face of the front-hole insulator; the rear insulator is installed on the socket housing to fix the jack.

[0035] When designing a high-frequency, high-current, oil-resistant connector, because the current has a skin effect in a high-frequency environment, the current distribution inside the conductor will be uneven, and the current will be concentrated in the "skin" part of the conductor. In other words, the current is concentrated in a thin layer on the surface of the conductor. The closer to the surface of the conductor, the greater the current density. The current inside the conductor is actually smaller. Therefore, the flat terminal jack 6 is used to meet the current requirements in a high-frequency environment, which can effectively reduce the influence of the skin effect on the current.

[0036] Since the product is in oil for a long time, the front insulator 4 and the rear insulator 7 are made of polytetrafluoroethylene, the sealing ring 2, the first O-ring 3, and the second O-ring 5 are made of silicone fluororubber, and the socket housing 1 and the cover plate 8 are made of nickel-plated aluminum alloy and radially sealed to meet the oil-resistant environment.

[0037] The specific assembly process is as follows:

[0038] Install the first O-ring 3 into the socket housing 1, as shown in FIG. Figure 2 3. Install the insulator 4 into the socket housing 1, as shown Figure 3 The second O-ring 5 is installed in the front hole insulator 4, as shown Figure 4 The jack 6 is inserted into the front hole insulator 4, as shown Figure 5 After the hole insulator 7 is installed into the jack housing 1, as Figure 6 As shown. Install the fixing plate 8 and screws 9 to fix the whole. Figure 7 Finally, install the end face sealing ring 2 to complete the assembly, as shown. Figure 8 shown.

[0039] After the connector is installed in the box, the oil in the box will not flow out of the connector due to the radial sealing method used by the connector; because the connector uses flat terminals, it can effectively ensure the current transmission efficiency under high frequency conditions.

[0040] The above description is only a preferred embodiment of the present invention and is used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
